SUGAR-CANE-SLICING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 405,909, dated J' une 25, 1889.

Application filed February 5, 1889. Serial No. 298,769. (No model.) A

To all whom it may concern:

Be it known that I, CARL RARE, of the city of Sangerhausen, in the Kingdom of Prussia and German Empire, have inventeda certain new and useful Improvement in Sugar-Cane- Slicing Machines, of which the following is a specification, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to an ilnproved slicing-machine intended for use in cutting up or paring sugar-cane, beet-root, and the like; and the object of my said invention is to so construct such machine that the fibers of the sliced or pared sugar-cane or other material are prevented from sticking' or collecting in the open longitudinal space in front of the cutting-edge of the paring-knife, an annoying difficulty constantly experienced in the use of machines of this class heretofore constructed, where the said spaces between the cutting-edges ofthe blades or knives and their opposite counter-pieces are obstructed after a short while by the collecting and adhering fibers, so that it becomes necessary from time to time to stop the machine and to clean the said spaces by removing` therefrom the obstructing fibrous mass. My invention is intended to obviatesuch difhculty and thus to increase the efficiency of the machine and save time and work by means of the novel construction, arrangement, and combination of the cutter-disk and cutter-box, as illustrated in the accompanying drawings, in which- Figure l is a transverse vertical section of my improved slicing-machine. Fig. 2 is a front elevation, and Fig. 3 is a top view, thereof. Fig. 4 represents a vertical transverse section on the line ozv a, Fig. 5, of the improved cutter-disk and one of the removable cutter-boxes inserted therein and carrying the adjustable cutter-blades or knives. Fig. 5 'is a top View of part of the said cutter-disk, showing the circumferential openings for the insertion of the said removable cutter-boxes. Fig. (3 is a top view of one of the said cutter-boxes drawn to an enlarged scale, the cutter-blade and its counter-piece being removed. Fig. 7 is a vertical longitudinal section of the same on the line e', Fig.

G. Fig. Sis a vertical transverse section on the line y ly, Fig. (i, showing the said cutterbox in position in the said cutter-disk, and Fig. 9 is a similar view on the line :c of Fig'. G, the cutter-blade or knife and its counter-piece being inserted and fixed in position.

b indicates the frame of the machine, in which the vertical shaft a is suitably journalcd, rotary motion being imparted to the latter by means of the bevel-gears c c', rotated by belt and pulley a on shaft CL2 of beveled pinion c. Upon the said frame b is mounted a receptacle (l, preferably of cast or wrought iron, which is provided with an outlet-opening and a hopper g communicating with the latter. The receptacle d is provided with a cover d', having rectangular openings for the inclined boxes 1f, which are fastened upon and pass through the said cover d. The inclined boxes 'L' are open both at their upper and lower ends, and serve for the reception of the sugar-canes u or other material to be pared, coming to rest upon and in contact with the cutter-disk e, fixed upon the said shaft a near its upper end and rotatin g therewith.

The cutter-disk e has a suitable number of circumferential openings c3, as shown in Fig. 5, each serving for the reception of a cutterbox 71, which may readily be inserted therein from above through a suitable opening in the cover ll, normally closed by the pivotcd lid or cover e2, Fig. t. The said openings e are confined laterally on three sides by the iron or other material of which the cutter-disk e is formed, and are open on the fourth side at or near the circumference of the said cutterdisk. In conformity with such construction of the cutter-disk the cutter-boxes h are likewise closed laterally on three sides and open on the fourth side, and they are inserted into the said openings c3, so that the open sides of both will coincide. Near the inner end, opposite to the open side, the cutter-box 7L is provided on its lower surface with a short projecting dovetail o', which allows of being pushed into a correspondingly-shaped groove in the cutter-disk c, when a hook-like proj ec- IOO tion q, forming the inner end of the cutterbox, will catch over and, under the action of the centrifugal force, lbear firmly against the inner surface of a projecting rib on the disk e, and thus prevent the box h from being flung out of the said disk when in rotation. The cutter-box h, when inserted in the opening e3 of the cutter-disk e, rests upon projecting fianges ei", forming part of the latter, Fig. 9, and the removable cutter-blade o is secured to the said cutter-box in the usual mann er by screws as shown. The letter p indicates the adjustable counter-piece for the cutter-blade or knife o, said counter-piece permitting of being raised or lowered, as usual, by turning the set-screw m, while the distance' between the sharp edge of the cutter o and its opposed counter-piece p allows of being reduced or widened in the usual and well-known manner by suitable set-screws, asv at m', passing with sufficient play through openings n in the cutter-box.

The sugar-canes u are placed in the inclined boxes fL', as indicated in Fig. l, and rotary motionis imparted to the cutter-disk e, as heretofore described, which will cause the cutters o to pare from the lower ends of the canes u elliptical slices 'a' of the form shown in Fig. 1. The cutter-disk e is formed with a circular horizontal central portion, re-enforced by ribs l and surrounded by a circular rib ci", beyond which the said disk terminates lin a horizontal peripheral upper portion, divided by the openings e3, and in a slanting or inclined peripheral lower portion e', formed on its upper surface with a series of radial triangular ribs Z, supporting thesaid peripheralupper portion of the disk e and radiating from the said annular rib 0*, as shown. The slices or parings u cut from the sugar-canes, as set forth, fall partly upon the slanting portion e', and thence upon the bottom of theI receptacle d, and partly directly upon the said bottom, and are swept automatically out of the receptacle d into the hopper g by means of a sweeping device consisting of the blades f4, attached to a sleevefs, loosely mounted upon the Vertical drivin g-shaft a, the said sweepingblades f4 being rotated with lower speed than the said shaft, and the cutter-disk e fastened thereto by means of the pinions ff f2 f3 of different diameters. Of these gears the small pinion f is rigidly attached to the shaft co and rotates the large pinion f on the secondary shaftf, which is thus caused to revolve with a lower circumferential speed than the shaft a. The shaft f carries another pinion f2 of small diameter, gearing with the large pinion f3 on the sleeve f5 of the sweeper f4, by which means the circumferential speed of the said sleeve f5 will become still lower than the speed of the shaft f6, so that the said sweeper f4 will be rotated with a speed comparatively much lower than that with which the cutterdisk eis revolved.

It will be seen from the foregoing description .that my improved slicing-machine differs from those as heretofore constructed essentially by the novel arrangement of the compartments formed by the ribs c* and l, the slanting portion e', and the 'peripheral horizontal upper portion of the cutter-disk e, supported by the said ribs Z and divided by the radial openings e3, said compartments being open toward the periphery of the said disk, and thus allowing the slices cut by those parts of the knives 0 overlying the said slanting portion to slide uniformly into the-receptacle d below it, while the said openings e3, being cut away near the periphery of the disk and having the cutter-boxes h, likewise open at the periphery, inserted therein, will not permit of any fibers settling in front of the knives and obstructing the spaces between the latter and their counter-pieces p, since by reason of the new arrangement, construction, and combination of these parts, as described, the said fibers, pressed constantly toward the periphery by the centrifugal force, will be flung out regularly at the open ends of the said spaces, thus leaving the latter unobstructed and in permanent working order.

I-Iavin g thus described ,myinventiom what I claim as new, and desire to secure by Letters Patent, is-

1. A rotary cutter-disk for ya slicing-machine, provided with a cutter and an inclined peripheral portion located below the cutter and receiving the severed slices therefrom, substantially as described.

2. A rotary cutter-disk for a slicing-machine, comprising an upper horizontal peripheral portion and a lower inclined peripheral portion having .radial ribs carrying the cutters and supporting the upper horizontal peripheral portion, substantially as described.

3. In a slicing-machine, a cutter-disk having an inclined peripheral lower portion and a horizontal upper peripheral portionsupported by ribs on the said inclined portion and divided by radial openings e3, intersect ing the periphery of the said upper portion,

substantially as and for the purpose specified. 4C. In a slicing-machine, the combination, with a cutter-disk having its periphery intersected by radial openings, of a cutter-box laterally open on one side and a cutter. carried by the cutter-boX, substantially as and for the purpose specilied. 1
